Application filed March 18, 1925. Serialm. 16,429;

My invention pertains to the withdrawal of air and water or the like by vacuum action from steam or hydraulic systems and more particularly to heating systems, fed by steam or vapor; and consists substantially in the construction, combination and arrangement of parts hereinafter set forth and pointed out more particularly in the claims.

in object of my invention is to provide a vacuum pump, the capacity of which is automatically varied with the conditions under which said mechanism is fed.

It is a primary object of my invention to provide a vacuum pump mechanism having a plurality of vacuum operated outlet valves in communication with the discharge of said mechanism, the vacuum operating instrumentalities of said valves being in communication with the incoming conduit of said mechanism, and adapted to respond to different vacuum tensions, whereby over feeding of said mechanism will correspondingly open one or more of said valves, and under feeding will close one or more of'said valves.

it is also an object of my invention to provice a vacuum pump mechanism having primary and secondary pumping means, with primary and secondary condensing means adapted to feed said pumping means, respectively; a plurality of vacuum operated outlet valves in communication with the discharge of said secondary pump means, the vacuum operating parts of said valves being adapted to respond to different degrees of vacuum and being in communication with the inlet of the primary condenser, whereby the outlet of the secondary pump means is controlled; and a jet means operated by the discharge of the secondary pump means, said jet means being fed from the primary condenser and adapted to discharge into the secondary condenser.

it is further object of my invention to provide a vacuum pump mechanism having primary and secondary pumping means, with primary and secondary condensing -.means adapted to feed said pumping means, respectively; a number of vacuumoperated outlet valves in communication with the disciarge of said secondary pump means, the vacuum operating parts of said valves being adapted to respond to different degrees of vacuum and being in communication with "Similar characters of reference designate similar parts throughout the several views. Referring to Fig. 1, the numeral 1 designates what I call the primary pump, which is fed from the lower region of the primary condenser 2 by means of the conduit 3 The discharge conduit 4 of said pump leads preferably to a heating boiler means (not shown), as used, in heating systems for resident and business buildings or the like. The

numeral 5 designates the return conduit from such heating system, and communicates mainly with the primary condenser 2. Said return conduit, primary condenser and the primary pump, etc, may be said to com prise a somewhat constant pressure and vacuum force means for causing the normal circulation of such heating system. For the purpose, however, of providing for the diifbrent degrees of suctions required on account of varying conditions in the heating system, as understood by those familiar with the art, I have provlded in conjunction with said primary pump and primary condenser, respectively, a secondary pump 6 and a secondary condenser 7, which receives its water orv vapor contents from the primary condenser 2, as will be understood, and may be said to more properly operate as a cooling means for the discharges from said primary condenser. The discharge conduit 8 of the secondary pump 6 has communication with the vacuum operated valves 9, 10, 11, and 12, said valves being conveniently arranged in series or in successive arrangement with each other, it being understood, however, that said valves may be also connected to separate branches leading from the discharge conduit 8 when ever desired. Said valves are conveniently operated by the diaphragm operated mechanisms 13, 14, 15 and 16, respectively, although dash pot, slide valve, or other vacuum operated mechanisms may be utilized in the operation of said valves, as desired. Said vacuum operated mechanisms communicate with the return conduit '5 by means of the conduit 17. Said valves are adaptedto-discharge into the conduits 18, 19, 20 and 21, respectively, which lead to the jets 22, 23, 2d and 25, respectively, and operate same. The intakes 2610f said jets are in ;'ommunica tion with the primary condenser 2, the motive stream of said injectors being directed from the discharges :of the aforesaid-valves by means ot theconduits27 to the nozzles28 of saidinj ec'tors, and said jets :thus serve to draw the vapor, .air etc. from said primary condenser, the water elements tending to settle in said secondary condenser the same as {in said primary condenser, While the .air and uncondensed vapor may discharge .thru the vent 29. In this way thesecondary pump 6 is conveniently fed with water, which settles in the lower region or" said secondary condenser, :the conduit 30 serving tor-suitably communicate said secondary condenser with the intake of said secondary ,pump.

TIhe above mentioned vacuum operated mechanisms 13, 14-, and 16 are adjusted by means of springs 31, which are adapted to respond to diifercnt degrees of vacuum, whereby under certain conditions all of the valves 39, 10, 1'1 and {12 will be closed and under certain other conditions all of said valves will %be open, it being understood that any number of said valves may be automatically brought into use in accordanc wvith the degrees of vacuum in said return conduit. When, therefore, the degrees of vacunm in the return conduit 5 is reduced by conditions in the heating system (not shown), the primary pump 1 does not have suflicient suction capacity to keep the degree of vacuum in said return conduit at a desired degree and the said vacuum operated mechanisms are adj ustec so that was the degree of vacuum becomes less, said mechanisms yield to their respective springs, which opens the respective valves, by which arrangement the aforesaid jets are brought into use, and being fed from the ,primary condenser 2 by means of the conduit 32, .as above mentioned, tend to combine the capacity of said secondary pump with said primary pump automatically.

Check valves are provided .-to unite the conduit 32 with the :said jets, to prevent reversing :of the movement thru the conduit 32 under any conditions which might arise.

Said primary and secondary pumps are conveniently driven by the electric motor 34L, said motor being conveniently disposed between said ,pumps and having its sha'it ends united therewith by means of the flexible couplings 35. It is understood, however, that any external means may be applied in driving said pumps.

A dome-like connection 36 is provided to connect the conduit 17 with the return conduit 5, for the purpose o1 preventingwater from passing into the conduit 17.

A conventional base means 37 is conveniently provided incommon with the primary and secondary condensers 2 and 7 the primary and secondary pumps {1 and t6, :and'the electric motor 34.

While I have illustrated 111 a general way,

certain instrumentalities which may be em will open one or more of said valves in accordance with such vacuum tensions, whereby intermediate working capacity of, the mechanism outlet is automatically maintained, as required.
